GATE.

SPECIFICATION forming part of Letters Patent o., 523,'782, dated July 31, 1894.

Application filed April 24, 1894. Serial No. 508329; (No model.)

and to enable the gate to be securely locked when closed to preventstock from opening it. The nvention consists in the construction andnovel combination and arrangenent of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the theclaim hereto appended.

In the drawings: Figure 1 is a perspective vew ofa gate constructed inaccordance with this invention, and shown closed. Fig. 2 is a transversevertical sectional View, the gate being partly open.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawngs.

1 designates a gate, provided with vertically extending end bars 2, andSuspended from a horizontal track bar 3, by means of grooved rollers 4,which are journaled in suitable hangers 5, Secured to and extendingupward from the upper ends of the vertical end bars of the gate. Thehorizontal track-bar is secured to and supported by a frame, which iscomposed of a horizontal topbar 6, vertical end uprights 7 and 8, and anintermediate upright 9. At opposite sides of the intermediate upright atsuitable distances from the gate are located posts 10, provided,adjacent to their upper ends, with suitable bearings, receiving ahorizontal rock-shaft 11, which is connected with and adapted to operatethe gate to open and close the latter.

The rock-shaft is provided at its ends with crank-handles 12 and 13, itpasses through a perforation 14:, of the intermediate upright, and it isprovided' at the opposite side of the gate from that on which theupright is located with an integral arm 15, to which is rigidlyconnected an oscillating bar 16. The oscillating bar 16 is providedadjacent to its lower end with a perforation 17, to receive therockshaft, and it is provided, intermediate of its ends, with a similarperforation 18, receiving the outer terminus 19 of the arin 15 of therock-shaft. ward at right an gles to engage the perforation 18, wherebythe oscillating bar is rigidly connected with the rock-shaft. The loweror inn'er end 20, of the oscillating bar 16 depends from the rock-shaft,when the oscillating bar extends upward, and fits against theadjacenthorizontal rail of thegate and forms a guide for the latter; andthe gate is also guided by a foot-board 21, of the supporting frane.

The rock-shaft passes through 'the space between the top rail 22, of thegate, and the adjacent rail; and the top rail 22 is extended rearward toform a horizontal arm 23, which has pivotally connected to its outerend, at 24, a connecting-bar 25, which is hinged, by a rule joint, orother similar or suitable form of hinge, to the upper or outer end ofthe oscillating bar 16. 4 r

When the gate is closed the oscillatng'bar lies in a horizontalposition, with the connecting-bar resting upon its upper edge, and a'straight brace is formed to prevent the gate from being opened bystock.

The handle 12 of the rock-shaft is preferably formed integral with it,and the other handle 13' is detachable to enable the parts to be readilyassembled; and after the rock-` shaft has been arranged in its bearings,the detachable handle is applied to it.

It will be seen that the gate is simple and comparatively inexpensive inconstruction, that it cannot sag, and that it may be readily operatedfrom the ground, or from a vehicle or horse.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this inve'ntion.

What I claim is The combination of a supporting. frame having ahorizontal track-bar and provided with a'n upright having a perforation,posts located at opposite eides of the upright and having bearingsarranged opposite the said perforation, a gate provided with rollers andThe outer terminus 19 is bent in- IOO the gate and forning a guide forthe same, and a conneoting-bar hinged to the onte' end 15 of theoscillating bar and pivotaily connected to the outer end of the arm ofthe gato, substantialiy as described. v

In testimony that I claim the foregoing as 'my own I have hereto affixedmy signaturein zo the presence of two witnesses.

CLINTON C. AIKMAN.
